Roger Federer will be attempting to reach yet another Wimbledon men's singles final as he faces Tomas Berdych at the All England Club in London on Friday.
The winner will battle either Sam Querrey or Marin Cilic, who play in the other semi-final on Centre Court.
Venus Williams stormed into the women's singles final on Thursday, where she's set to meet Garbine Muguruza on Saturday.
Williams was ruthless as she beat home favourite Johanna Konta on Centre Court, winning 6-4, 6-2 with a dangerous display of power.
Muguruza will face the veteran after she defeated Magdalena Rybarikova in minimal time, prevailing 6-1, 6-1.
Here are Thursday's confirmed results:
- Venus Williams def. Johanna Konta — 6-4, 6-2
- Garbine Muguruza def. Magdalena Rybarikova — 6-1, 6-1
Here are Friday's semi-final matches:
-  Sam Querrey vs.  Marin Cilic
-  Roger Federer vs.  Tomas Berdych
Federer will believe he is in pole position after watching the top names fall at Wimbledon 2017.
The Swiss superstar has showed his usual composure and strength of character, and he now faces Berdych in the last four.
Berdych skipped through after Novak Djokovic suffered injury in their quarter-final encounter, with the Serb following a number of top names to exit due to fitness problems.
Milos Raonic was caught in Federer's headlights in their last-eight match, and the veteran completed victory in straight sets, 6-4, 6-2, 7-6(4).
Querrey has been the surprise of the tournament, but the big hitter has added an extra dimension to his game on grass.
The No. 24 seed defeated Andy Murray, but the reigning champion was clearly carrying an injury as he exited in five sets.
Cilic has been impressive in the final weeks ahead of Wimbledon, and he is a natural when it comes to the environment of Centre Court.
Federer and Cilic are the highest ranked seeds remaining, and both men will expect to meet in the final.
Cilic has an excellent chance of adding his second Grand Slam title to his career haul after winning the U.S. Open in 2014.
However, Federer will be the man to beat from this point forward, and his form has been impressive during the second week.
Berdych has been a top-class performer throughout his career, but it is questionable whether he can defeat his iconic opponent at present.
Querrey is the wild-card talent remaining, but it is unlikely he will eliminate Cilic at the business end of the competition.
Cilic has incredible grit and determination, and avoiding Murray in the semi-final will be viewed as a huge bonus to his ambitions.
- Federer to win in straight sets
- Cilic to win in four sets
